Sigurdsson joined Spurs from Hoffenheim in July 2012 but struggled to establish himself in the starting side.

The Iceland midfielder has signed a four-year contract and says he wants to help Swansea back into Europe next season.

"The main aim for the club is obviously to stay in the Premier League but we want to push on even further and get the club back into the Europa League like they were last season," Sigurdsson told Sky Sports News.

"Hopefully we can finish in the top half of the table."

Sigurdsson continued: "I really enjoyed my time here last time.

"I know the club, I know the manager, I know the players and I obviously know the fans and the city as well so that wasn't that difficult for me.

"Leaving Tottenham is because I enjoyed my time there as well for two seasons but Swansea were interested and that's the club I want to play for."

Crystal Palace were reported to have had a bid accepted for Sigurdsson but the playmaker insists Swansea's style of football persuaded him to choose the Welsh club.

"The way they play football was a big factor," he said.

"They've got some great players here.

"Hopefully we'll be a lot better than we were last season and get back to the top half of the table where Swansea belong."
